COTE St. LUC, Que. -- The visiting Université de Montreal stunned McGill 9-7 in the opener of a best-of-three semifinal, Saturday, in Game 1 of a doubleheader in the Canadian Collegiate Baseball Association's Northern Division playoffs at Gary Carter Field.

The results was also UdeM's second win in the last three meetings with McGill and put the four-time defending national champions on the edge of elimination, heading into the second half of the twin-bill, slated to start at 3:30 p.m. on Saturday.

Montreal, which had a 7-6 edge in hits and committed a whopping six errors, exploded for six runs in the top of the first inning and three more in the second. Then they held on for dear life as McGill chipped away with one run in the first, three in the fourth and three more in the fifth.

Kevin Spenard was the winning pitcher for Montreal. He allowed seven runs on six hits and four walks over 4.1 innings, striking out four. Beaulieu threw two and two-thirds innings in relief out of the bullpen. Mathias Beaulieu-Labbe recorded the last eight outs to earn the save.

Sam Greene took the loss. He allowed four hits and six runs (five earned) over two-thirds of an inning.

Six different players had hits for Redmen, namely Jared Kersh, Dominic DeFelice, Jonathan Duforest, Chester Dixon, Troy Shepherd, and Emerson Dohm each managed one hit to lead McGill.

Montreal collected seven hits on the day, led by Ludovic DuFour, who went 2-for-4 with four RBIs and one run scored. Teammate Samuel Lazzer also had a multiple-hit soiree, going 2-for-4 with four RBIs and a run scored.
